Mexican singer CRISTIAN CASTRO has taken aim at his estranged wife after she hinted that the hunk is gay.

Valeria Liberman publicly questioned the star’s sexuality as their divorce battle heated up recently, and Castro is refusing to take her comments lightly.
He rages, “If she says I’m gay, she should back it up with proof.

“It’s a HUGE lie. I don’t think she has any evidence that I am gay.”

Castro, 33, has also reprimanded Liberman for talking openly about their failed marriage: “I think it’s really sad and a little unwise for couples to speak badly when they break up.

“Everything that happens in a marriage is behind closed doors and should remain there.” (Whatever happens in Vegas stays in Vegas)
